Okay, i thought about starting a new topic specifically for my latest purchase, but decided to tag a reply onto the end of this so as to keep all the "Linux Compatibility" in one place.
DISCLAIMER: Just in case i say something that sounds "odd", I really want to point out that (as a first time poster) that I am in no way against how Novatech chooses to run their business. Novatech, and the staff therein have always been nice to me, and very accommodating of my various requests.
So, this Linux business is really not as difficult as some people make out. While it is true that sometimes a person needs patience for certain hardware to find support within the Linux Kernel, ofttimes unless you're running something brand-spanking-new or just plain 'out there', it'll install and run just fine. At times, you do need to be willing to do research. At other times, you do need to be able to compromise or plain do without, until you find the support you need for the hardware you want.
I have plenty of experience with this; I've been running Linux as my only OS since 1996. I remember having to buy external modems (no drivers necessary) when all the internal (win)modems relied on Windows drivers. Nvidia over Radeon... etc.. Nowadays, it tends to be far simpler.
I ask myself regularly "Am I just one of those people that Linux always works for?". Indeed, I have plenty of friends that have tried, and failed, to run various strains of GNU/Linux. I do understand, really I do. Linux, depending on the Distro, is not for the faint-hearted... but the rewards are great!
That Novatech do not want to state in any way shape or form that their stock will support Linux (knowing full well that Intel compatibility has been very good for a very long time... knowing that Nvidia compatibility has been very good for a very long time, etc..) is understandable because as soon as they say "Hey, guess what!?...." it opens them up to all sorts of hassle that they, as a business, don't want/need (I respect that and I've never burdened them with my personal prefs). But that doesn't mean that their gear is useless to us that travel a different OS road.
As I need to go to bed, here's the bit that is important:
I needed a new laptop so, yesterday, I purchased the N1639. Everything works:
Keyboard, track pad, network (wired and wireless), Bluetooth, sound, suspend and all-but-one Fn combo (the F1 Fn 'track-pad on/off doesn't doesn't work).
UEFI'd Ubuntu 17.04, clean installed on the (changed in BIOS from 2nd drive to 1st) M.2 SSD. 500mb HDD as storage. Full disk encryption. No hassle and all done in the time it took me to make and drink a cuppa.
Ya'see, it's all Intel.. Why on Earth would anybody think that it wouldn't work?
I've been doing this for years and (with a healthy dose of #ymmv) go purchase and have fun!
p.s. Just like Novatech, I offer no promises or support
